Carbon dating non organic materials

That is, they take up less than would be expected and so they test older than they really are.Furthermore, different types of plants discriminate differently.These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.

Obviously, this works only for things which were once living.

This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years.

Anything over about 50,000 years old, should theoretically have no detectable C.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

C ages of soil organic matter or its fractions are always younger than the true ages of soils due to continuous input of organic matter into soils.
